本篇博客部署是創建在Hadoop高可用基礎之上的，關於Hadoop高可用部署請參考：https://www.cnblogs.com/yinzhengjie/p/9070017.html。本篇博客是將Hadoop的高可用配置和zookeeper徹底分佈式結合使用！git
一.分佈式協調框架web
1>.分佈式框架的好處算法
a>.可靠性： 一個或幾個節點的崩潰不會致使整個集羣的崩潰。 b>.可伸縮性： 能夠經過動態添加主機的方式以及修改少許配置文件，以便提示集羣性能。 c>.透明性： 隱藏系統的複雜性，對用戶體現爲一個單一的應用。
2>.分佈式框架的弊端shell
a>.競態條件： 一個或多個主機嘗試運行一個應用，可是該應用只須要被一個主機所運行。 b>.死鎖： 兩個進程分別等待對方完成。 c>.不一致性： 數據的部分丟失。
二.Zookeeper簡介apache
1>.Zookeeper的做用json
答：爲了解決分佈式協調框架的一些弊端，就出現了zookeeper軟件，它是目前大數據中比較流行的分佈式協調框架。windows
2>.Zookeeper的特點
a>.名字服務： 標識集羣中的全部節點，節點可以向其註冊併產生惟一標識。 b>.配置管理： 存儲配置文件，以便共享。 c>.領袖推選機制： 就是根據其自身的算法推選出leader和follower。 d>.鎖和同步服務： 當文件進行修改，會將其進行加鎖，防止多用戶同時寫入。 e>.高有效性數據註冊： 一個節點是數據不能超過1M,這個規則是遞歸的，換句話說，每一個節點及其子節點的存儲空間大小不能超過1M。
3>.本篇博客部署zookeeper架構圖
4>.領袖推選機制介紹
在選舉leader節點時，首先會比較事務id，其次比較myid，若是集羣中已經有一半機器參加選舉，那麼次leader就是整個集羣中的leader。
爲了方便理解，我畫了兩幅圖，便於理解上面的一句話，當事物id一致時推選leader以下：
當事物id不一致時推選leader以下：

五.初學者遇到問題最霸道的解決方案：（這種暴力解決方式適合我這樣測試集羣中使用，若是你的架構跟個人同樣，那麼這種方法也適合你）
舒適提示：若是你要格式化集羣，最好是將以前的數據目錄更名，若你沒有刪除或修改集羣以前的數據目錄，格式化後的版本信息仍然是上一次沒有格式化的集羣版本信息喲！這樣極可能致使你的DataNode或者NameNode進程啓動不了，或者存在剛剛啓動不一下子進程就掛掉了！
